The caddisflies and mayflies that live in streams metamorphose into adults while in the water; for this reason, they are more important to trout, which have a chance to snag both the naiad and the adult. Also, because they require clean, well-oxygenated water, their presence is a sign of good water quality. Adult stoneflies have wings, but they usually stay on the banks of streams and rivers and eat algae or lichen. When stoneflies disappear from a stream where they used to live, it is a sign that something is wrong with the water.
